The OJPEGPostDecode function in tif_ojpeg.c in LibTIFF 3.9.0 and 3.9.2, as used in tiff2ps, allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted TIFF image, related to "downsampled OJPEG input."

The OJPEGReadBufferFill function in tif_ojpeg.c in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an OJPEG image with undefined strip offsets, related to the TIFFVGetField function.

Integer overflow in the TIFFroundup macro in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF file that triggers a buffer overflow.
